The hose for our central vacuum was in crisis - the cord was fraying, the connector knob had fallen out, it had been duct taped - it was time for a change.
After a quick Homestars search, I found Vacuums Plus and called Marco, who spent far more time answering all my questions than such a minor matter deserved.
Because I got such a good feeling, I asked him about replacing our existing vacuum, and once I gave him the serial number he was able to tell me how old it was (pretty old - 15+ years if I remember correctly), and after sending him a photo of where it lives he recommended a Nilfisk of about the same size.
However, it is substantially more powerful, and significantly quieter!
The best part was the installation - the guy he sent was a pro!
He not only installed the unit, including humouring me (after he was basically done) by adding the port that is normally for the garage so that I can clean my crawlspace, he then tested all of the ports to ensure they were maintaining a good seal, and happily replaced one that was failing, and then happily replaced all of them when I saw how nice the new ports looked, running back and forth to his car each time.
To top it all off, when I asked about a muffler (even though it was already quieter than before), he was out to the car again and set me up with a good quality muffler.
So glad I found Vacuums Plus!
